Description
STBC
The STBC (
Space-time block coding
) technique allows increasing
data transfer reliability even for portable devices equipped with poor
antennas (smartphones, pads, etc.) due to using several data streams
and processing several versions or received data.
Move the switch to the right if you need to use the STBC technique.
B/G protection
Available on the
2.4 GHz
tab.
The 802.11b and 802.11g protection function is used to minimize
collisions between devices of your wireless network.
Select a value from the drop-down list.
•
Auto
: The protection function is enabled and disabled
automatically depending on the state of the network (this
value is recommended if your wireless local area network
consists of both 802.11b and 802.11g devices).
•
Always On
: The protection function is always enabled (this
setting can substantially lower the efficiency of your wireless
network).
•
Always Off
: The protection function is always disabled.
Short GI
Guard interval (in nanoseconds). This parameter defines the interval
between symbols transmitted when the router is communicating to
wireless devices.
•
Enable
: the router uses the 400 ns short guard interval. Only
for the wireless network operating modes which support
802.11n and 802.11ac standards (see the value of the
Wireless mode
drop-down list on the
Settings /
Wireless Network
page).
•
Disable
: the router uses the 800 ns standard guard interval.
Beacon Period
The time interval (in milliseconds) between packets sent to
synchronize the wireless network.
RTS threshold
The minimum size (in bytes) of a packet for which an RTS frame is
transmitted.
Frag threshold
The maximum size (in bytes) of a non-fragmented packet. Larger
packets are fragmented (divided).
DTIM period
The number of beacon frames between sending DTIM messages
(messages notifying on broadcast or multicast transmission).
